Description

Illuminated tubular strip for three-dimensional structures and stretched textile three-dimensional structure comprising said strip

Technical Field

The present invention relates to the field of stretched textile three-dimensional structures, such as in particular false walls, false roofs, false partitions or decorative structures.

The invention more particularly relates to an illuminated belt plate for a stretched textile three-dimensional structure comprising said belt plate to which a stretched textile is attached.

Background

From patent FR2985298 a false wall is known, which is backlighted by at least one light source in the form of a light emitting diode incorporated in a strip and which consists of at least one translucent flexible sheet, the edge of which is suspended, said edge being provided with suspension means suspended from a frame, wherein said frame consists of a strip formed by abutting profiles and comprises receiving elements able to cooperate with said suspension means to keep said flexible sheet tensioned.

However, the strap plates described in the above-mentioned applications have various disadvantages. The strap according to the prior art makes it impossible to obtain a rounded, rounded or curved shape. Furthermore, the edges formed by these band plates protrude, which can be harmful and unsightly, depending on the desired end result.

It is an object of the present invention to solve these problems by providing a lighting strip for backlighting a three-dimensional structure.

Disclosure of Invention

For this purpose, and according to a first aspect, the invention proposes a belt plate for stretching a textile three-dimensional structure comprising at least one light source incorporated in the belt plate. The strap comprises two adjacent recesses separated by a tenon, said recesses being designed to receive fastening elements of a stretch fabric, wherein each recess comprises a base, an outer side wall and an inner side wall forming said tenon, said outer side wall defining a peripheral wing of said strap.

In the present application, a side wall of the recess opposite to a side wall (the inner side wall) of the recess forming the tenon is defined as an outer portion.

The strap is made of any material, for example, a metal such as aluminum or a plastic such as polyvinyl chloride (PVC).

The strip plates according to the invention are butted to form a profile, wherein the profile contributes to the frame of the three-dimensional structure in which these strip plates are used. When the stretch fabric is installed, the strap panels are not visible. The strip allows the formation of three-dimensional structures, all of whose surfaces may be visible or indeed decorative, depending on the desired result. In addition to the non-projecting edges, the band plate also makes it possible to obtain a curved or rounded shape. This produces a perfect aesthetic result and avoids any risk of the stretched fabric breaking or tearing due to the fabric contacting the upper and surrounding belt plates. Likewise, the wear of the stretched fabric is slowed down. The strip can also be used to tension fabric to form false roofs as well as false walls, both of which are visible on their surface. Also, the particular shape of the strip does not result in any projection when the leds are illuminated.

The stretch fabric is preferably translucent or capable of transmitting light. They may be textured, colored, monochromatic, printed, colored or any decorative type of feature, including having regions that do not transmit light, to obtain a light and shade effect.

The light emitting diodes may be of any color and of any power.

Advantageously, the peripheral surface of the lighting strip panel is provided with at least one receiving recess for a light source.

According to a particular configuration, the band plate comprises a receiving recess having an opening opposite to the recessed opening. It is also possible to provide the strap plate with two further receiving recesses which are arranged on either side of the receiving recess with an opening opposite to the opening of the recess. Advantageously, the receiving recesses arranged on either side of the receiving recess having an opening opposite the opening of the recess are equally spaced therefrom.

Advantageously, the peripheral flap of the strip is connected to the end of the outer side wall of the adjacent recess by a rounded joint, wherein the outer surface of the peripheral flap defines in cross section a rounded portion against which the stretch fabric is placed to create a space, wherein the outer surface of the opposing peripheral flap incorporates the light source.

It is to be understood that the strap comprises two peripheral wings, wherein a first peripheral wing extends from a rounded joint with an outer side wall of a recess and a second peripheral wing extends from a rounded joint with an outer side wall of an adjacent recess. The two peripheral wings are not necessarily symmetrical about the tenon separating the two recesses. The cross section of the outer surface of the first peripheral flap defines a rounded portion that acts as a support for the stretch fabric. The curved shape of the wing portions avoids the fabric being torn and allows a wide variety of three-dimensional results to be formed and more space to be created between the stretched fabrics without any risk of tearing.

Advantageously, the peripheral flange is arranged to define a receiving recess for the light source. In this configuration, the peripheral flange is advantageously symmetrical with respect to the tenon.

When the cross-section of the band plate is generally circular or truncated circular in shape, the rounded portion may extend over, without limitation, at least one quarter of the circle having a radius generally equal to the depth of the recess.

According to an alternative form, the rounded portion extends at least over a semi-circle with a radius substantially equal to the depth of the recess.

According to another alternative, the rounded portion extends over 3/4 that is rounded with a radius substantially equal to the depth of the recess.

According to an embodiment, the peripheral flap opposite to the peripheral flap supporting the stretch fabric comprises a receiving recess for at least one light source.

It is to be understood that the recess comprises, in addition to the light source, a power supply system for the light source.

According to a variant, the shape of the receiving recess is complementary to at least a lateral portion of the light source, so that the light source follows the contour of the strip in cross section.

In an embodiment, the notch forms a right angle.

The light source is neon, fiber optics, or any other light source known to those skilled in the art. Preferably, the light source is formed by light emitting diodes incorporated in the ribbon board.

According to a preferred embodiment of the invention, adjacent recesses and notches of the band plate are arranged in mutually parallel planes.

This particular arrangement of the notches allows for tensioning of one or both fabrics. When two fabrics are installed, one stretch fabric is attached to each recess, and one fabric may be partially wrapped around the strap plate, for example, 180 °; the other fabric may be tensioned parallel to the first fabric, defining a gap between the two fabrics, the gap having the height of the belt plate. The light sources are preferably arranged towards the gap between the fabrics, thereby avoiding any projection of the belt plate on the stretched fabric. It will be appreciated that the gap between the two fabrics may be greater than or equal to the height of the belt plate, depending on the shape of the final three-dimensional structure. The gap may be widened as the distance from the band plate increases.

According to a preferred embodiment, adjacent recesses separated by a tongue comprise shoulders for retaining fastening elements of the stretch fabric, wherein said shoulders are on the outer side walls of the recesses and/or on each side of the tongue.

However, according to a preferred embodiment, the shoulder of the outer side wall of the recess is arranged opposite with respect to the shoulder of the wall of the tenon.

It is to be understood that the recess includes shoulders on the wall that form a retention stop for securing the stretch fabric. The stretch fabric includes fastening elements such as hooks or any other means known to those skilled in the art that allows the fabric to hang from the strap plate and tension the fabric.

The invention also relates to an illuminated three-dimensional structure comprising at least one profile consisting of abutting illuminated strip panels, said illuminated strip panels being covered by a stretch fabric.

Detailed Description

The belt plates shown in fig. 1 to 4 are designed to form profiles for three-dimensional (in particular, decorative) structures, on which a stretch fabric is arranged.

Fig. 1 shows a first embodiment of an illumination strip plate 1 with a substantially circular cross section.

Fig. 2 shows the illumination strip panel 1 of this first embodiment with a substantially circular cross-section, from which two

stretch fabrics

2, 3 are suspended.

The illumination strip plate 1 of this first embodiment has a substantially circular cross-section. The lighting strip panel 1 comprises two adjacent recesses 4, 5 of equal size separated by a tenon 6. The recesses have the same depth and width. They each comprise a base, an inner side wall and an outer side wall forming the sides of the tongue 6.

These recesses 4, 5 are laterally symmetrical with respect to the tongue 6. The outer side walls of the recesses 4, 5 comprise shoulders 7, 8 oriented towards the cavity of the recess. These shoulders 7, 8 are arranged opposite shoulders 9, 10 on each side of the tongue 6. These shoulders 7, 8, 9, 10 form a stop for retaining the

fastening elements

11, 12 of the

stretch fabrics

2, 3 on the three-dimensional structure, as shown in fig. 2.

Since the band is configured with a particularly substantially circular cross section, the outer side walls of the recesses 4, 5 form

peripheral wings

13, 14 of the band, the outer surfaces of which are curved and follow a circle with a radius substantially equal to the height of the tenon and thus to the height of the recess. The junction 15 between the upper end of the outer side wall of the recess and the outer surface of the peripheral flap is rounded so as not to damage the stretch fabric attached in the recess. One of the peripheral wings 13 extends over a circular 3/4 with a radius equal to the depth of the depression 4. The peripheral flaps 13 serve as support for the stretched fabric 3 and give it a rounded shape.

The lighting tubular strip 1 according to the invention comprises a recess 16, in which recess 16a light emitting diode is incorporated. The notches 16 are cut in the peripheral flaps 14, opposite the fabric-supporting peripheral flaps 13.

The notch 16 forms a right angle towards the inside of the band plate. The right angle of the recess preferably consists of a small edge 16a and a large edge 16b, wherein the large edge 16b is parallel to the walls of the recesses 4, 5 and the side of the tongue 6. The large edge 16b has a height substantially equal to the depth of the recesses 4, 5. In addition to the light emitting diodes, the recess also receives the power supply system of the diodes.

Furthermore, the band plate comprises a cavity 17 below the recesses 4, 5, wherein, in the illustrated embodiment, said cavity 17 is a parallelepiped. The strip plates according to the invention are butted to form a profile by screwing the cavity 17 onto a guide (not shown) to form a part of a frame of a three-dimensional structure.

Figure 2 shows a tubular strap according to the invention with two

stretch fabrics

2, 3 suspended thereon. The first stretch fabric 2 is suspended in the first depressions 5 by the hooks 12 and forms a surface of a three-dimensional structure. The second stretched fabric 3 is suspended in the second recess 4 adjacent to the first recess 5 by the hooks 11 and forms the other surface of the three-dimensional structure. The stretch fabric 3 is arranged around the belt plate at substantially 180 so that the

stretch fabric

2, 3 completely conceals the belt plate 1. The two

stretch fabrics

2, 3 define the boundary of the gap between the stretch fabrics, into which the light of the light emitting diode incorporated in the notch 13 of the strip is diffused. The above embodiments are non-limiting and the gaps between the fabrics may vary depending on the final three-dimensional structure. Thus, the second fabric is more or less curled around the band plate.

Fig. 3 shows a second embodiment of the present invention. The illumination strip plate 18 of this second embodiment has a generally circular cross-section. The band plate 18 comprises two adjacent recesses 19, 20 of equal size separated by a tongue 21, wherein the recesses have the same depth and width. They each comprise a base 22, an inner side wall 23 and an outer side wall 24 forming the sides of the tenon. These recesses 19, 20 are laterally symmetrical with respect to the tongue 21. The outer side wall 24 of the recess 20 includes a shoulder 25 oriented toward the cavity of the recess. These shoulders 25 are arranged opposite shoulders 26 provided on each side of the tongue 21. These shoulders 25, 26 form stops for retaining the fastening elements of the stretch fabric on the three-dimensional structure.

Since the band 18 is configured with a substantially circular cross-section, the recessed outer side wall 24 forms a

peripheral wing

27, 28 of the band, the outer surface of which is curved and follows a circle with a radius substantially equal to the tenon height and thus to the recess height. The junction 29 between the upper end of the outer side wall 24 of the recess and the outer surface of the peripheral flap is rounded so as not to damage the stretch fabric attached in the recess. In this second embodiment, the

peripheral flaps

27, 28 are symmetrical about the tenon and define a recess 30. The recess 30 comprises a bottom 31 parallel to the bottom 22 of the recess 19, 20 and two

side walls

32, 33. Furthermore, the length of the bottom 31 of the recess 30 is equal to the distance of separation of the outer side wall between the two recesses 19, 20. The side walls 33 of the recess 30 are in the same plane as the outer side walls 24 of the recess 20. Thus, each wing extends in an arc from the junction 29 between the upper ends of the recessed outer side walls 24 to the lower ends of the

side walls

32, 33 of the recess.

The recess 30 is designed to receive a light source characterized by a light emitting diode with its power supply system. The recess 30 can also cooperate with the frame of the three-dimensional structure. The strap further comprises means for attaching the strap to a frame of a three-dimensional structure.

Fig. 4 shows a third embodiment of an illumination strip according to the invention.

Like the strip of the above-described embodiment, the lighting strip 40 of this third embodiment has a substantially circular cross-section and comprises two

adjacent recesses

41, 42 separated by a tenon 43, the

recesses

41, 42 advantageously being of the same size. These

recesses

41, 42 are of the same depth and width and each comprise a base 44, an inner side wall 45 and an outer side wall 46 forming the sides of the tenon. The

recesses

41, 42 are laterally symmetrical with respect to the tongue 43. The outer side wall 46 of the

recess

41, 42 comprises a shoulder 47 oriented towards the interior of the relevant recess. These shoulders 47 are arranged opposite shoulders 48 provided on each side of the tongue 43. These

shoulders

47, 48 form stops for retaining the fastening elements of the stretch fabric on the three-dimensional structure.

Since the band plate 40 is configured to have a substantially circular cross section, the outer side walls of the

recesses

41, 42 form the

peripheral wings

49, 50 of the band plate, the peripheral surface (outer surface) of which is curved. The junction between the upper end of the outer side wall of the recess and the outer surface of the peripheral flap is rounded so as not to damage the stretch fabric attached in the recess.

In this embodiment, the band plate 40 comprises on its peripheral surface three

recesses

51, 52, 53 (advantageously, these recesses are straight recesses) able to receive light emitting diodes and the related power supply system.

More specifically, one of the notches 51 is located opposite the

recesses

41, 42 in the radial direction. Similar to the recess 30 of the strap 18 of the second embodiment shown in fig. 3, this recess 51 comprises a bottom 510 parallel to the bottom 44 of the

recess

41, 42 and two

side walls

511, 512. Advantageously, the width of the bottom 510 of the recess 51 is substantially equal to the distance between the outer side walls 46 of the two

recesses

41, 42, while the

side walls

511, 512 of the recess 51 are on the same plane as the outer side walls 46 of the

recesses

41, 42.

The other two

recesses

52, 53 are located on either side of the recess 51. Advantageously, the

notches

52, 53 are positioned at equal distances from the notch 51 and are arranged diametrically opposite each other. Therefore, they have openings facing each other so as to extend on planes substantially perpendicular to the extension plane of the openings of the notches 51, respectively. The

recesses

52, 53 each comprise a bottom 520, 530 and two

side walls

521, 522, 531 and 532 parallel to the bottom 51 of the recess 51. The bottom of each of the

recesses

52, 53 extends parallel to each other and perpendicular to the bottom 510 of the recess 51.

Advantageously, the band plate 40 comprises a longitudinal cavity 54, the cavity 54 having a substantially rectangular cross section, interposed between the

recesses

41, 42 and the notches 51 arranged opposite the recesses. The cavity 54 extends throughout the entire length of the band plate 40. The cavity 54 has the same function as the cavity 17 of the belt plate 1 of the first embodiment.

The invention also relates to an illuminated three-dimensional structure comprising at least one profile consisting of strip panels according to the invention, said strip panels being butted. The stretch fabric is suspended from the butt-profiled strip sheet to form an illuminated stretch fabric three-dimensional structure. The three-dimensional structure may be a false roof, a false wall, a floodlight, a fanciful shape, a decorative element or any other three-dimensional lighting object.

Of course, the present invention is not limited to the exemplary embodiments shown above.
